Patent CA-2204710-A1 (CA)
Inventor: WHITE BRIAN M
IPC: B25C1/04
Filed: 1997-05-07
Abstract: A pneumatically operated fastener driving device includes a pilot pressure operated main valve movable from a normally closed position into an opened position closing an exhaust path and allowing a supply of air under pressure to be communicated with a piston chamber to initiate and effect the movement of a piston and fastener driving element through a fastener drive stroke. First passage structure is provided between a pilot pressure chamber and an exhaust port.  A secondary valve member is mounted with respect to the first passage structure so as to be movable between an opened position permitting communication between the pilot pressure chamber and the exhaust port and a closed position preventing communication between the pilot pressure chamber and the exhaust port.  Second passage structure communicates the piston chamber with the secondary valve member and with the exhaust path.  An operative cycle is initiated upon actuating a trigger member to exhaust pilot pressure in the pilot pressure chamber through the exhaust port causing the main valve to move to its opened position thereby initiating the fastener drive stroke.  Pressure over the drive piston in the piston chamber communicates with the secondary valve member to move the secondary valve member to its closed position preventing communication between the pilot pressure chamber and the exhaust port thereby causing the main valve to move to its closed position.  The secondary valve member permits one full cycle of operation to be performed while the trigger member remains actuated thereby minimizing exposure of the fastener driving element and thus, damage thereto.

Patent CA-2208951-A1 (CA)
Title: Ergonomic hand tool
Inventor: SCHOOR WOLFGANG
IPC: B25D1/04
Filed: 1997-06-27
Abstract: The ergonomically improved hand tools include an improved handle which has a handle grip portion set at an angle to the tool head. The angle at which the handle grip is set to the remainder of the tool handle is a compound angle arranged such that the handle grip portion extends laterally of the remainder of the handle and angles downwards vertically into the hand when being gripped. This compound angle has the benefits of the Bennett handle as well as brings the tool head into alignment with the forearm of the individual using the handle which the Bennett handle fails to do. The improved hand tool handle is adaptable for use with most currently used hand tools and may be employed in any application where its use would be appropriate. The ergonomically improved hand tools provide an ergonomically redesigned hammer having the improved handle which reduces the risk of repetitive strain injuries. An extended fulcrum point is located at the top of the hammer head for improving the nail extracting characteristics of the hammer claw.      The hammer claw has claw members that are angled relative to one another enabling the claw to access nails located in corners, along baseboards and at other locations where two surfaces meet at an angle. The hammer handle as well as the improvements discussed above includes the further improvement of being made from laminated materials which increases the strength of the hammer handle and helps dampen vibration. An improved paint brush and scissors are also provided. Both the paint brush and the scissors include the improved handle arrangement.

IPC: H04B7/185
Filed: 1996-11-29
Abstract: In a mobile satellite system, a system for providing satellite communication between multiple users in a virtual network arrangement includes first and second mobile earth terminals (METs) responsively connected to and registering with the mobile satellite system. The first MET selects a virtual network identifier (VN ID) representing a virtual network group including the first and second METs to establish voice communication therewith and transmits the VN ID to a central controller. The central controller receives the VN ID from the first MET, validates the first MET for communication, validates the VN ID, allocates a frequency for the virtual network group, and broadcasts the message to the virtual network group including the second MET informing the virtual network group of the allocated frequency and the voice communication associated therewith.      The second MET tunes to the frequency in response to the message broadcast by the central controller.

Patent CA-2221611-A1 (CA)
Title: Pool sentinel
Inventor: PALLER MICHAEL SCOTT
IPC: E04H4/06
Filed: 1998-01-28
Abstract: This invention relates to a passive means to provide full time monitoring of unattended swimming pools, where the unit activates remotely and is self contained resting on the surface of the water. Signals received from the motion of wave action which cause the cone to tilt and contacts to close, or sounds received from the hydrophone as a result of agitation in the water result in the circuit activating the power supply pulling in a timer relay contactor which subsequently supplies power to a transmitter. This application of power activates the transmitter which then transmits information to an in-house receiver which converts the signal into a command for operation of Claxton horns or other audio notification devices including phone dialers etc.
